Solubility: Gypsum is reasonably soluble in water, that has a solubility of about 2 grams for each liter at 25°C. Curiously, gypsum exhibits retrograde solubility, indicating its solubility decreases as h2o temperature increases – contrary to most salts that turn out to be much more soluble in very hot drinking https://www.propanraya.com/id/produk/eco-gypsum-ee-4050
